title: Further studies of sulfoxide-reducing enzyme system.
abstract: Various kinds of flavoenzymes such as NADPH-cytochrome c reductase, NADH-cytochrome b5 reductase, xanthine oxidase, lipoamide dehydrogenase and NADH dehydrogenase supplemented with their electron donors exhibited the sulfoxide reductase activity in the presence of a partially purified soluble factor from guinea pig liver. The present study suggests that new electron transfer systems in which the soluble factor functions as an electron carrier coupled with flavoenzymes described above are responsible for the sulfoxide reduction.
